Essential Oils are highly concentrated essences of plants which have been extracted either by steam distillation, alcohol extraction or cold compression. Herbal Advantage guarantees all of our essential oils to be 100% pure and unadulterated. Our high quality oils can be used for aromatherapy, massage, cosmetics, and in some cases, for food applications. Essential oils are highly concentrated so use sparingly and with caution. In most cases, essential oil should never be applied directly to the skin or ingested internally.
